TL;DR
This study finds that systematic lymph node dissection during lung cancer surgery increases the risk of chronic cough compared to lymph node sampling.
Contribution
The study identifies specific lymph node clearance techniques that influence post-surgery chronic cough in non-small cell lung cancer patients.
Findings
Systematic lymph node dissection is associated with higher chronic cough risk than lymph node sampling.
Clearing more lymph nodes and dissecting upper and lower mediastinal regions increases cough risk.
Chronic cough negatively impacts patients' physical, psychological, and social well-being post-surgery.
Abstract
背景与目的 肺癌是所有恶性肿瘤中致死率排名最高的恶性肿瘤,其中非小细胞肺癌(non-small cell lung cancer, NSCLC)占所有肺癌的80%-85%。肺叶切除术和淋巴结清扫术是最主要的治疗手段之一,而淋巴结清扫术作为重要组成部分,其清扫方式和清扫范围的选择一直备受关注,可能影响术后并发症,尤其慢性咳嗽的发生。本研究旨在探讨淋巴结清扫方式和清扫区域对行肺叶切除术的NSCLC患者术后慢性咳嗽的影响,为优化手术策略、减少术后慢性咳嗽提供临床依据。方法 回顾性收集2020年12月至2023年12月中国科学技术大学附属第一医院收治的365例接受肺叶切除术治疗的NSCLC患者临床资料,对其临床特征及术后慢性咳嗽之间的关系进行分析。收集患者术前1天及术后8周2个时间节点的中文版莱斯特咳嗽问卷(Mandarin Chinese version of the Leicester Cough Questionnaire, LCQ-MC)评分数据。根据淋巴结清扫方式分组,探讨淋巴结清扫方式与肺叶切除术后患者慢性咳嗽之间的关系。另外,根据术后是否存在慢性咳嗽分为慢性咳嗽组和非慢性咳嗽组,探讨围手术期资料、淋巴结清扫方式及淋巴结清扫区域是否是其影响因素。结果 行肺叶切除术患者中,系统性淋巴结清扫组较淋巴结采样组患者更易发生术后慢性咳嗽(P<0.05)。系统性淋巴结清扫组患者术后8周LCQ-MC量表评估显示,其心理、生理、社会及总分均显著低于淋巴结采样组(P<0.05)。多因素分析提示:麻醉时间、手术位置、淋巴结清扫方式、是否行上纵隔区淋巴结清扫、上纵隔区淋巴结清扫数目、是否行下纵隔区淋巴结清扫和清扫淋巴结总数目是NSCLC患者术后慢性咳嗽的独立危险因素(P<0.05)。结论 NSCLC患者行肺叶切除术治疗时,选择淋巴结采样较系统性淋巴结清扫可显著降低患者术后慢性咳嗽的发生风险。清扫上纵隔区和下纵隔区淋巴结以及清扫淋巴结的数目可能增加患者术后咳嗽的发生风险,降低患者术后的生活质量。 Comparison of general clinical data between…
